We have a lot of tasks run to a bewildering schedule across multiple servers. We use cron, of course. But maintaining the schedule is painful. Very painful.
We’ve tried committing copies of the crontab to a repository, but they’re almost never up-to-date.
And worse, if I need to do something even moderately complex like, say, schedule a job to run every two weeks, cron starts to get complicated.
But things just got better.
